Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety during the repair.

2. Inspect and Replace Brake Rotors

Remove the Wheel
- Use a lug wrench to loosen and remove the lug nuts.
- Lift the vehicle using a jack and secure it with jack stands.
Inspect Rotors
- Remove the brake caliper by unscrewing the caliper bolts using a socket set.
- Remove the brake pads to access the rotor.
- Inspect the rotor for warping using a dial indicator. Replace if warping exceeds manufacturer specifications (usually 0.002 inches).
Replace Rotors
- If needed, remove the rotor by unscrewing the retaining screws and sliding it off.
- Install the new rotor and tighten retaining screws to manufacturer torque specifications (usually around 10-15 ft-lbs).

3. Inspect and Replace Brake Pads

Install New Brake Pads
- Apply brake grease to the backing of the new brake pads.
- Insert the new brake pads into the caliper bracket.
Reattach Caliper
- Reposition the caliper over the pads and secure it with caliper bolts, tightening to manufacturer specifications (usually around 25-30 ft-lbs).

4. Wheel and Suspension Check

Inspect Tires
- Check for uneven wear or damage on all tires.
- Rotate tires if necessary and ensure they are balanced.
Check Suspension
- Inspect control arms, tie rods, and ball joints for any wear or damage.
- Replace any worn suspension components as necessary.

5. Reassemble and Test

Reattach Wheel
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and then torque the lug nuts to the manufacturer specifications (usually around 80-100 ft-lbs).
Test Drive
- Conduct a test drive to ensure the steering wheel shake has been resolved.
